This website provides information on tropical coastal ecosystems: world distribution maps, plant species lists and ecosystem functions. We hope this information contributes to a deepened understanding of tropical coastal ecosystems and stimulates further discussion on these ecosystems. The website is a very good resource for maps of mangroves, species descriptions, and species lists by country. Finally, the use of satellite-based remote sensing methods can substantially facilitate the mangrove monitoring, especially in forests that are extensive and remote.
